What are the parts of an electrical circuit?, Battery, bub, wires and switch, What are the two terminals of a battery?, The positive terminal (+) and the negative terminal (-), What are the parts of a bulb?, Glass casing, metal filament and base (with a metal casing and a tip), What is a closed circuit?, When a bulb in an electric circuit lights up, we say that current flows through it. When a path is connected correctly with no gaps, current can flow through the circuit. Both terminals of the battery must be correctly connected to the metal parts of the bulb. , What is an open circuit?, When a bulb in an electric circuit does not light up, we say that no current flows through it. When a circuit is not connected correctly or has gaps, current cannot flow through the circuit. Both terminals of the battery must be correctly connected to the metal parts of the bulb. , What are electrical conductors?, Any material that allows current to flow through them (Metal), What are electrical insulators?, Any material that does not allow current to flow through them (Ceramic, fabric, glass, plastic, rubber, wood), What are circuit diagrams?, Representation of electric circuits using symbols, The amount of current flowing through a bulb depends on..., 1) The number of batteries in a circuit and 2) The number and arrangement of bulbs in a circuit, The more the batteries in a circuit, the __________________ the bulb. , brighter, The more the bulbs in a circuit arranged in series, the __________________ the bulbs., less bright, The more the bulbs in a circuit arranged in parallel, the bulbs are _______________________., equally bright .
